At first I couldn't find the build your own trip. It only shows up after you have entered in segments in the multiple destinations search and gotten results.
It got me past the 5 segment limit, but gave me a higher fare than travelocity (expedia gave $572 and travelocity gave $528, for the same exact flights, and UAL.COM won't even display the flight on the second segment to let me make the selection, even though a separate one way search shows the flight, and thus priced the result at $758)
